In fact, the typical CEO made a whopping 312 times their median employees' salary in 2017, according to the Economic Policy Institute.

But some chief executives earn salaries that are seemingly disproportionate to their company's shareholder returns. A 2019 report from As You Sow, a nonprofit focused on shareholder advocacy, ranks the most "overpaid" leaders on the S&P 500.

To figure out who's overpaid, As You Sow calculated the ratio of CEO pay in 2017 to total shareholder return at each company, as well as the companies where the most shares were voted against the CEO pay package (the first ratio was weighted double).

Ronald F. Clarke, CEO of Fleetcor Technologies Inc., which makes corporate payment products, took the No. 1 spot. According to the analysis, Clarke is overpaid by 263%. His expected pay based on Fleetcor's performance is $14,483,985; his actual pay in 2017 was $52,643,810. Per the report, 86% of shareholders voted against Clarke's pay package.

Because there was a change in CEO at a few companies (Oracle Corp., The Walt Disney Co., TransDigm Group, Inc., and Discovery, Inc.), the salary of the higher-paid CEO was counted.

Below, we've listed the 25 most overpaid CEOs according to As You Sow, as well as each of their salaries, the median employee salary at their company, and the pay ratio.
